Fantech's ceiling mount ventilation fans offer adjustable airflow settings and an energy-efficient DC motor ensure lower electricity consumption than traditional exhaust fans. A ceiling radiation damper adds an additional layer of protection to the building application, reducing the spread of flames and heat in the event of a fire. The fans are constructed using 26-gauge galvanized steel to prevent corrosion and feature thermal overload protection and a soft-start feature on specific models, aiding longevity and reliability.
